Joe Bowser commented on CB-4057:
--------------------------------
What you are describing can never happen with the CordovaActivity without
extremely heavy modification. I'm not sure that this patch is necessary, or
solves the issue for CordovaWebView. If someone is using the WebView with
other native views, they should be using CordovaWebView as a component with
their own CordovaInterface, not with CordovaActivity.
> Lately created webview can cause application crash

> If the webview is lately created because application uses other native views
> to display data and the user press a key then the application will crash.
> Therefore, onKeyUp, onKeyDown and onActivityResult in CordovaActivity should
> first check the webview is not null before interacting with it. By the way,
> other places in CordovaActivity where appView are protected to prevent NPE.
